He says only a handful of the commonwealth's 500 districts recognize discrimination based on gender identity.

"Over half of school districts in Pennsylvania protect on the basis of sexual orientation, but still we're not at 100 percent," Goodman says. "We need to be at 100 percent of districts protecting against discrimination, regardless of who you are."

Goodman says his group is putting together a policy school districts can use as a model for protecting transgender students from discrimination.
